HOSE-COUPLING.

Specification of Letters Patent.

Patented J an. 14, 1913.

Application tiled August 23, 1911. Serial No. 645,472.

T o all whom it may concern Be it known that I, Lao Coa'ras. a citizenof the United States, residing at Pittsburgh, in the county of Alleghenyand State of Pennsylvania, have invented new and useful Im rovements inHose-Couplings, of which t ie followin is a specificatlon.

This invention ie ates to hose couplings or connections and particularlyto a connection for cou ling a rubber iose or pipe to a water disc argefaucet or spigot.

The object of the invention is to provide a device of this characterwhich is simple of construction, inexpensive of reduction, adapted tosecure the hose firm v in position, and Ca able of being readily appliedand remove and of engaging faucets or spigots varying to some extent insize or s ape.

A further object of the invention is to provide a device of thischaracter which is adapted for engagement with different sizes of hosetubes or pipes.

The invention consists ofthe features of construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accoinpanying drawings, in which- Fi re 1 is a sideelevation of a faucet, showin the application of the invention. Fig. 21s a central vertical section through the coupling or connection. Fig. 3is a top plan view of the same. Fig. 4 is a side view of a. modifiedform of connection ada ted for engagement with two sizes of hose. ig. 5is a similar view of another modified forni of connection ada ted forengagement with a removable nipp e section.

The cou ling or connection comprises a tubular bod)v or casing 1 havingat its lower end a contracted nipple 2 forming a flange` or shoulder 3and provided with external annular bevel faced ribs 4 over which the endof the hose is designed to be slipped and wired or otherwise secured inposition. Lining said body or casing is a tubular rubber asket adaptedto engage and receive the ischarge nozzle 6 of the faucet or s igot 7.The lower end of this gasket liears against the shoulder 8 and saidgasket is internally tapered for a firm frietional enga ement with thenozzle 6. In order to olli the gasket firmly in position, the upper endof said gasket is turned outwardly to form a cufll 8 which ineloses theupper end of the body or casing and is clamped against.

the saine by a split clamping member or ring fhthe ends 10 of which areperforated for the passage of a bolt 1l provided with a retaining nut12, whereby the clam `)ing ring may be drawn as tightly as desire toclamp the sleeve in position. The said clamping meinber oi ring 9 isprovided with inturned upper and lower flanges 13 and 14 to bear againstthe extremities of the cnfl" and preventthe cuff from slip )ing or thegasket from becoming displace in the application and removal of theconnection to and from the nozzle of the faucet. To further assist inholding the connection in place, a latch member is provided which isformed of a single piece of spring wire having an end or arm 15 providedwith an eye 16 pivotally enga ing the bolt 1l between the ends of the camping ring, and having its o posite end or arm bent at right an les totie arm 15 and formed to provide a iook to engage the inlet neck 18 ofthe faucet or spigot, whereby the latch is pivotally connected with theclampin ring so that the hook is adapted through its pivotal connectionand spring action to be adjusted to slide and snap over the neck 18 tofasten the connection in place against possibility of casualdisplacement. The extremity of the hook is formed to provide a fingerpiece for convenience in manipulating and the intermediate portion ofthe latch is provided with a s .ring coil 19 adapted to permit the hookto ave an increased range of motion longitudinally and laterally forengagement with the inlet necks of different sized faucets, or faucetsin which the necks vary in length and diameter. It will be seen that theconstruction described provides for the ready and quick aiplication andrelease of the connection an( its firm and secure retention in place tohold the hose in place for service. The clamping ring may be removedfrom the body or casin at anv time when it is desired to detaci an oldgasketand apply a new one.

In the construction shown in Fig. 4 a ribbed nipple 4 having portions Q0and Q1 of different diameters is provided for the application of twodifferent sizes of hose pipes, thus ohviating the necessity of employing difl'erent sizes of connections for the two sizes of hose pipesmost commonly used.

ln Fig. 5 the body or easing l is shown provided with a threaded end 2Qand abutment flange 28, whereby threaded nipples of diierent sizes maybe applied to one and the same connection for the attachment thereto ofdifferent sized hose pipes.

Having thus described the inventlon, what I claim as new is:

A hose connection comprsin a tubular gasket nteriorly seated in a tubuar retainer, said tubular retainer having a reduced, ribbed and hoseholding nipple, and a flan d clamping band with a wire bracket lntcmember, said latch member having a l C. M. GmsoN.
